If you are experiencing panic attacks, the best medication would be an antianxiety agent (a benzodiazapame) such as
Klonopin. I take
Klonopin for generalized anxiety disorder. At first I felt very sedated. This could have been due to two headache medications I was on (am off of now), or my body hadn't adjusted to it. Now, I'm not sedated from it. For me, Klonopin helps a bit, but for panic attacks, it's supposed to work wonders.
